I pay $45 +tip at a local salon. I've tried lots of different stylist and I really like the one I'm with now. A cut and color can be anywhere between $85 and $145 depending on what has to be done. I go about once every 3 months.
My DH on the other hand spends more than I do overall. He goes to the barbershop weekly at $17 a trip. His hair is thinning on top so he keeps it super short and it looks funny if he goes more than about ten days without cutting it. I've told him he should just go ahead and shave it all off but he's holding out as long as he can.
$85, plus tip for the cut, which is pretty standard for a high-end salon in my major metro area. Highlights are $135, I think. After having had many, many bad haircuts in my life, it is absolutely worth it - my hair is fine and it seems to be easy for less skilled folks to screw it up. My stylist and colorist are perfectionists and I only go about 4x/year.
